The Promise object represents the eventual completion (or failure) of an asynchronous operation and its resulting value.

The <vkern> SVG element allows to fine-tweak the vertical distance between two glyphs in top-to-bottom fonts. This process is known as kerning.

The <feConvolveMatrix> SVG filter primitive applies a matrix convolution filter effect. A convolution combines pixels in the input image with neighboring pixels to produce a resulting image. A wide variety of imaging operations can be achieved through convolutions, including blurring, edge detection, sharpening, embossing and beveling.

The AsyncGenerator object is returned by an async generator function and it conforms to both the async iterable protocol and the async iterator protocol.

Programming languages all have built-in data structures, but these often differ from one language to another. This article attempts to list the built-in data structures available in JavaScript and what properties they have. These can be used to build other data structures.

The font-family attribute indicates which font family will be used to render the text, specified as a prioritized list of font family names and/or generic family names.

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

The glyph-orientation-vertical attribute affects the amount that the current text position advances as each glyph is rendered.

The Proxy object enables you to create a proxy for another object, which can intercept and redefine fundamental operations for that object.

The font-style attribute specifies whether the text is to be rendered using a normal, italic, or oblique face.
